I need to unlink my steam account.

[I need to unlink my steam account.]

Hi.
I need to disconnect my steam account from this bohemia account. I created an unit with another account.
I've been searching in the forum but all I found was a moderator linking other people's topics regarding this issue.
I've checked those topics but it lead me to nothing but a waste of time thanks to the moderator. 😃
I need instructions on how to unlink my accounts :)

Hello.
I Tried these lines: -high -cpuCount=2 -exThreads=3 -maxmem=2047 -noPause -nosplash -skipintro -world=empty

p.s: "-cpuCount=2 -exThreads=3" Are just for dual cores
